Plastic Injection Molding Processes for Your Production

Over 20 Proven Injection Molding Technologies for More Profitability

With ENGEL’s injection molding processes, you can produce parts precisely, reworking is not necessary. No matter if you strive for a transparent or multicolored part surface, or you want to complete the part with patterns and engravings. The combination of technologies allows you to design the products with high mechanical properties and attractive surfaces at the same time. With appropriate transparency, sensors can be placed optimally protected behind cover panels. We always find the right injection molding process for you.

At ENGEL, you receive a production cell, that is ready to use: from the injection molding machine, the robot and the conveyor systems to peripheral equipment. Immediately after the machine and mold acceptance testing, you start production with the selected injection molding process. You can rely on the best part quality, stable injection molding processes and high productivity.

Variety of materials can be used

With our injection molding machines, you can process thermoplastics and thermoplastic elastomers, as well as thermosets. A wide range of applications is possible. Each manufactured part has different requirements for production. Our experts determine what technology is suitable and choose one of our more than 20 proven injection molding processes. Transparent materials, for example, can be manufactured to precise optical lenses using injection compression. We make use of the full performance spectrum of materials.

Optimal settings thanks to innovative software solutions

We use innovative software solutions to optimize the injection molding process of your part. Assistance systems ensure increased weight consistency, optimum mold temperature control and important setting values - such as clamping force - are automatically suggested by the machine controller. In more challenging injection molding processes, various data has to be monitored. Our software solutions precisely show parameters with deviations.

User support for stable production processes

The Application Engineering team does not look at the challenges of injection molding individually, but as part of the overall process. Our experts perform trials and afterwards, take care of the ideal design of the machines for your injection molding process. We support you in manufacturing the first part and then optimize the production process. The goal: an efficient, stable and cost-effective manufacturing solution.
